About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X100S
The SCT32X200X100S is a double-acting multi-position tandem cylinder providing four fixed rod positions: 0 mm (fully retracted), 100 mm, 200 mm, and the total travel of 300 mm. Each piston section delivers a push force of 402 N at 0.5 MPa, driven through a 12 mm diameter rod with M10x1.25 threads, making it suitable for light-duty sorting or diverting tasks where three distinct extended stops are required.
This model includes a built-in magnet, designated by the 'S' suffix, allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for non-contact position feedback. The cylinder body measures 233 mm in its retracted state and features a 21 mm adjustable air cushion on each section to manage end-of-stroke deceleration. Operating pressure ranges from 0.15 to 1.0 MPa with standard TPU seals rated for -20 to +70 °C.

| Total travel | 300 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 21 mm |
| Max stroke / section | Up to 500 mm standard |
Specifications follow the official AirTAC SCT (multi-position) datasheet. SCT is available in bores 32–100; each of the two sections has a 500 mm max standard stroke (800 mm max). Confirm against the product label before installation. Thread options: PT (standard) / G.
Stop Positions (4)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 200 mm |
| P2 (section 2) | 100 mm |
| P3 (both extended) | 300 mm |
Positions are set by pressurising section 1, section 2, or both. With equal strokes you get 3 distinct positions; with unequal strokes you get 4.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
Force is per actuated piston section (single-piston, same as the SC bore): push uses the full bore area, pull subtracts the rod area. Size with a safety margin.

Where the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X100S Is Used
Three-Position Diverter Gate
Uses the 0, 100, and 200 mm stops to direct small packages onto three separate conveyor lanes. The 300 mm total travel position can serve as a fourth bypass or reject lane.
Multi-Depth Stamping Ejector
Provides two distinct ejection depths (100 mm and 200 mm) plus a full-extend clearing position (300 mm) for clearing different part thicknesses from a stamping die.
Two-Step Component Feeder
Advances parts in a magazine with a 100 mm primary feed and a 200 mm secondary push, using the magnet sensors to confirm each intermediate stop before the next cycle.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X100S the Right Cylinder?
Selecting the SCT32X200X100S is ideal when a machine axis requires four discrete mechanical stops without the complexity of servo control. The 200 mm and 100 mm stroke combination allows for a two-step feed or a three-position diverter gate. If higher force is needed, stepping up to the 40 mm bore increases per-section push force to 628 N at 0.5 MPa. For replacement, ensure the new unit matches the 32 mm bore, the exact 200 mm and 100 mm strokes, PT port threads, basic mounting, and the integrated magnet option.
Given the 200 mm stroke on the first section, consider external guides if the rod experiences significant side loading, as the 12 mm rod is sized primarily for axial thrust. The cylinder is double-acting and requires continuous pressure to maintain any of its four positions; it will not hold a load if air pressure is lost or valves are centered, so a pilot-operated check valve is necessary for static load holding.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 200 + 100 mm suit your layout?
- ✓ Required force at your working pressure
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Plumb the two sections to the correct valves for each stop.
- check Adjust end cushion screws for smooth stops.
- check Use SCT mounting accessory (FA / FB / CA / CB / LB).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X100S FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 100 mm (stroke 2 extended), 200 mm (stroke 1 extended), and 300 mm (both strokes extended, total travel).
Yes, it often can. The SCT32X200X100S replaces a dual-cylinder setup for two-step positioning in a single compact body. Ensure the replacement matches the 32 mm bore, 200 mm and 100 mm strokes, PT ports, and the -S magnet option for sensor compatibility.
